I'm issuing a custom signal called imageLoaded of CPP that contains an image as a parameter. How can I connect this signal to a slot in QML and can access the image...?
Hi, I have a url on CPP file to analyze my weather data, but the current location its on my main qml trought PositionSource attachedObject and I save in a property string latitude and a longitude of chain ownership, how can I use it on my url in the file c
I am new to waterfalls and QML and yesterday I tried to port native QtWidget app to waterfalls, but it does not. The problem is, I add some buttons to the container in QML main file and coded my custom slot function which should be executed when the user click some button. But I don't know how to connect the clicked() signal to my function from the custom location.
When using
Connect (CloseButton, signal(Button::clicked()),this,slot(on_closeButton_clicked()));) or connect (exitButton, SIGNAL (clicked ()), this, SLOT (on_exitButton_clicked ())); I get error "unable to connect SIGNAL (null) to SLOT (on_closeButton_clicked ()) ' on all the buttons.
Hello. My nam is Kieu. I have a problem and and we hope you guys can helo me. I just bought a Gateway desktop all-in-one computer and tried to connect it to the TV via the HDMI port, but I could not get signal on my TV. Help, please. Thank you very much
Hi David,
Thanks for posting your query in Microsoft Community Forum!
According to the description of the problem, it seems that you are unable to get the signal when you connect the TV to HDMI port.
I will certainly help you with this issue.
Here are some steps that you can try in order to solve the problem.
Step 1. First you need a video cable to make the physical connection. For a better image quality, you need to connect the computer to the TV using standard VGA ports or via DVI to HDMI Cable provided your TV supports these ports.
Step 2. Open thedisplay settings' ' in your Vista computer and Activate the output to the TV screen. You can reflect the content of your computer on the TV or extend the display as a double screen control.
Step 3 Pick up your TV remote and switch to "External inputs" in the menu. You need to change the value by default "Video 1" to a different selection which may be "HDMI 1" or "video 2" depending on how you made the connection. "
Important: Make sure you connect the cable to the TV before turning on the computer, because sometimes it may not recognize the external display.
You may also change the resolution of your TV screen using the display settings in your panel of control remains the image may appear distorted.
QML to signal received (somehow this must be duplicated?)
signal cameraCaptureCompleted (string imageLink) onCameraCaptureCompleted: {} Console.Debug ("link to the image:" + imageLink);
}
The onCameraCaptureCompleted never triggered. The console.debug ("link to the image:" + imageLink); did not show anything.
Thanks for your help!
OK, I went back and looked at your provided code again and I see you try to put your location of onCameraCaptureCompleted on the Page, which certainly won't work, since the Page is not the class that has the cameraCaptureCompleted signal. I suggest one of these three approaches:
Of course, all these examples assume that you have successfully exposed the App class to QML with qmlRegisterType(). The signal you want to respond to being on the App class, you must place your location, or connect the App::cameraCaptureCompleted signal to your location explicitly.
Before ask you, I searched for answers to this question, but I have not found a satisfactory example.
I have set up a service network in C++ that performs queries to REST against a backend. An example query would be to download a given element, the id of the item.
Once the item is extracted, I emit a signal such as:
itemReceived(QString& itemId, QString& item);
My question is how can I wire this signal to the slot in a QML page so that the status of the answer? I tried to connect the signal on the Qml in C++ slot, as follows:
I know to connect my click event of the button to NavigationPane.popanddelete in the native SDK,
I want to implement this feature in QML, how to implement it.
My struct QML is something like this:
P
MyHeader.QML
Container{
Button{
objectName:"BackButton"
onClicked:..//how to write here
}
}
MyPage.QML
Container{
MyHeader{
}
Container{
}
}
within C++
QmlDocument *qml = QmlDocument::create("MyPage.qml");
AbstractPane *mypage= qml->createRootNode();
// Button *button = alertPage->findChild("BackButton");
//QObject::connect(button,SIGNAL(clicked()),this,SLOT(onPreviousClick()));
m_pagePane->push(mypage);
Thanks in advance...
Hello
I want everything first, make sure that you know about the properties of the component in QML. If you have inserted a page in your navigation pane and want to have a back button seems natural, you can use the following code in your definition of QML Page {}:
This will insert a lower bar filled with a previous button following a consistent style.
If you want to raise the pop event from the QML document via manual button (no), in the property of your onClicked button, you can simply call pop on the handle of your navigation pane.
for example Button {} ID: buttonTest objectName: "buttonTest. text: "text". onClicked: {} _navPane.pop (); }
Please note that in both cases, you have exposed the handle of "_navPane" in your C++ code with subsequent calls (assuming that m_SidePaneContentQML is the name of your page with the back button):
Put all these files in the same folder, run qmake in there, it will produce a Makefile. Run make and it comes out a binary executable called myslots. That and your code works.
I don't have a lot of changes, I'll let you step through the code yourself to find out what I did. Look at the documentation for help.
I have not tested this Momentics, nor Alpha PlayBook/Dev. But I'm 100% sure the code works, since I ran it myself.
I have laptop with HDMI and Toshiba Camileo P30. I see the image of the camera on my laptop as if connect the camera to the TV?
Should what software I use (cause that nothing happens, when I connect my camera)?
Hello
Is your laptop supports HDMI IN port? If this isn't the case, then you can not do this. You need an HDMI port which received signals as a TV or external monitor
Could someone help me and advise me as to what head I need to connect a camcorder from Panasonic M10 full size on my Equium L20 laptop I would like to transfer my old tapes of children on a dvd, the camera has three taken phono Conect to a video or TV, but how do I connect to laptop
Hello
Well, I think that without a 3rd PCMCIA card you won't be able to connect the camcorder to Equium L20. To my knowledge this unit supports only an output s-video and there aren t any taken to receive signals from the camera :(
I have a model extreme A1521 airport and a model express airport A1392 and upgraded my OS to El Capitan. I want to use the express as an Extender for the extreme because my old House is long and has thick walls. My problem is that Airport utility will not 'see' the express, regardless of its proximity to the main router (extreme). I tried to move and reset.
Of course, as soon as I get the utility to see, I need instructions on how to configure the express as a booster for my extreme.
Any ideas?
Unplug the Express and put it in the same room as the AirPort Extreme.
Put power on the Express for a few minutes, then hold down the reset button on the back of the Express for 7 to 8 seconds and release.
Allow a minute for the Express to restart
Click the WiFI icon at the top of the screen of the Mac
Look for an announcement of the new AirPort base station
Click directly on the AirPort Express Terminal
When you click on AirPort Express, the "Wizard" will open and take a few seconds to analyze things, and then see a screen that looks like the figure below, except that you can see your cameras.
Type a short and simple name that you want to call the Express
Click next
The installation wizard will take care of everything for you
When you see the message Setup is complete, unplug the Express and move to halfway between the AirPort Extreme and the area of the House that needs more coverage of wireless signal
Turn on the Express and you're all set
Important note... the Express to expand the quality of the signal it receives. About half of the potential speed on the entire nextwork is lost when you extend using a wireless connection between the airports.
It would be much better if you could connect the Express to the extreme by using wired Ethernet wired, permanent, since there is no loss of signal via the Ethernet cable and there is always a lot of loss of signal through the air, the (thick walls especially) walls, ceilings, etc.
We can connect the output of the sensor directly to the DAQ hardware or any interface necessary? If so wat kinda necessary interface?
How to change the sensor output to match entry-level data acquisition?
If the sensor output beyond daq range is provided. What are its effects? pls answer
-It depends on your signal and the type of device you have. Your DAQ provides a package of signals? Also, what type of signal you want to measure? You must select DAQ that matches that. Take a look at the following before you start:
-You will need to use external circuitory to match the input of data acquisition range.
-You could damage the unit.
If you have any other questions, please after return. And, don't forget to give more details about your configuration, the hardware and what you're trying to do.
I am trying to hook up a TV with S-Video with my laptop. I plug the cables & when I go to the screen & my 2nd monitor/tv is not an option. It's only as 1 to my laptop screen. I'm trying to detect & still no solution...
Most of the standard definition TVs supports only video composite or S-video connections. If your computer supports one of them, you may be able to connect it to your TV. However, both of these connection types will result in displays that are not as sharp as the results you get with an HDTV or a standard computer monitor.
The following scenarios show you how you can connect a computer to a standard definition television:
If your computer has this type of output port
It should work with this type of TV input port
By using this type of cable
Composite video
Composite video
Composite video composite video
S video
S video
S video S-video
Connect your computer to your TV
After that you have the right cable, follow these steps to connect your computer to your TV:
Turn off your computer and place it near your TV. Unplug the monitor, but leave the mouse and keyboard connected.
Connect the video cable appropriate to your computer's output to your TV.
Turn on your TV and set it to the input that matches the output on your computer. You may need to refer to the supplied with your television user's guide for instructions on how to do it.
Turn on your computer.
You should see windows displayed on your TV. If the screen looks stretched, or part of the screen seems cut off, you will probably need to adjust the reference resolution in Windows. For more information, seeGetting the best display on your monitor.
If Windows is displayed on your TV, you will need to reconnect the computer to your monitor and adjust the screen resolution before connect you to your TV.
Notes
Cables VGA, DVI and component video don't support audio signals. However, HDMI cables are supported audio signals, but not all HDMI-enabledvideo audio support cards. If your TV has an audio input, you might be able to connect an audio cable separated from computersound directly to the TV card. Otherwise, you need to connect the audio signal to a different device, such as external speakers or your stereo. For more information about sound cards, cards seeSound: frequently asked questions.
If your computer does not support the type of video connection you need, you may be able to install a newvideo card that has the right connection.
